Daily and Weekly Cleaning Tasks
The Litter Robot works best when you clean it regularly, and most of that work takes just a few minutes. Every day, empty the waste drawer at the bottom of the unit—this is the black plastic bin that slides out from underneath. Lift it straight out, dump the clumped litter into a trash bag, and slide it back in. If you have multiple cats or one cat that uses the box heavily, you may need to empty it twice a day.
Once a week, wipe down the inside bonnet (the dome-shaped top) with a dry cloth or paper towel to remove dust and litter particles that stick to the plastic. Check the black rubber flap at the entrance—this is the most-touched part of the machine—and wipe it clean as well. These quick weekly passes keep odor down and prevent buildup that can interfere with the sensors.
Key Takeaways
- Empty the waste drawer daily or twice daily depending on how many cats use the box, and wipe the bonnet and entrance flap weekly with a dry cloth.
- Run the full clean cycle once a month by pressing the button on the control panel, which takes about 25 minutes and cleans the globe and all internal parts.
- Clean the sensors and the globe itself with a soft, dry cloth or a slightly damp microfiber cloth—never use water inside the machine or on electrical parts.
- Replace the carbon filter every month and the bonnet gasket every three to six months to keep odor control working and prevent litter from escaping.
- If the unit stops cycling or the light blinks red, check that the waste drawer is fully inserted and the bonnet is seated properly before calling for help.
Running the Monthly Deep Clean Cycle
The Litter Robot has a built-in cleaning cycle that you should run once a month. Press the button on the control panel (usually the top of the unit) to start the cycle. The globe will rotate slowly and the unit will run through a series of movements for about 25 minutes. During this time, the globe scrapes itself clean and the internal mechanisms move through their full range to dislodge stuck litter and dust.
Make sure the waste drawer is fully inserted before you start the cycle—if it is not seated all the way, the machine will not run. The cycle is loud and will vibrate, so run it when you are home and can hear if something sounds wrong. After the cycle finishes, empty the waste drawer again because the cleaning process will have loosened material into it.
Cleaning the Globe and Sensors
The globe is the clear plastic chamber where the litter sits. Over time, litter dust and urine residue cloud the plastic and can interfere with the infrared sensors that detect when a cat is inside. Once a month, remove the globe by unlatching the bonnet and lifting it away from the base. Wipe the inside and outside of the globe with a soft, dry cloth or a microfiber cloth slightly dampened with water—do not soak it or use soap.
The sensors are small black or dark-colored rectangles mounted on the inside of the globe or on the base. Wipe them gently with a dry cloth. If the unit is not cycling properly or the light blinks red, dirty sensors are often the cause. Never use water directly on the sensors or any electrical part of the machine. If you cannot see the sensors clearly, check your unit's manual or the Litter Robot website for the exact location on your model.
Replacing Filters and Gaskets
The carbon filter sits in a cartridge at the top or side of the unit and absorbs odor. Replace it every month, or sooner if you have multiple cats or notice odor returning. The filter is inexpensive and takes 30 seconds to swap out—straightforward pull the old one out and slide the new one in. Litter Robot sells replacement filters, and generic carbon filters of the same size often work as well.
The bonnet gasket is a rubber seal that runs around the bottom edge of the dome. It keeps litter from spilling out during the cycle. After three to six months of use, it can crack or harden and stop sealing properly. If you see litter escaping around the edges during a cycle, the gasket is likely worn. Replacement gaskets are available from Litter Robot and take a few minutes to install—you straightforward peel off the old one and press the new one into the groove.
Dealing with Stuck Litter and Jams
If the globe does not rotate smoothly or the unit makes grinding sounds, litter may be stuck in the mechanism. First, empty the waste drawer completely. Then press the button to start a cycle and watch what happens—if the globe moves but slowly, or if it stops partway through, turn off the unit when ready by unplugging it.
Remove the bonnet and globe and look inside the base for clumps or debris wedged in the gears or around the rotating parts. Use a small brush or old toothbrush to gently dislodge any stuck material. Do not force anything or use water inside the base. Once you have cleared the debris, reassemble the unit and try the cycle again. If the problem persists, contact Litter Robot support—the motor or gears may need professional attention.
Preventing Odor and Mold
Odor usually comes from a full waste drawer, a clogged carbon filter, or a dirty globe. The waste drawer should never sit more than a day or two before emptying, even if it does not look full—urine soaks into the litter and creates smell. Replace the carbon filter monthly without waiting for odor to return; prevention is easier than cleanup.
Mold can grow in the waste drawer if it gets wet or sits in a damp place. Always empty it completely and let it air dry before reinserting. If you live in a humid climate, wipe the drawer dry with a cloth before putting it back. Never pour water into the unit to clean it—the Litter Robot is not waterproof, and moisture can damage the motor and sensors. Stick to dry cloth cleaning for all internal parts.
Troubleshooting Common Problems
If the unit does not cycle at all, first check that the waste drawer is pushed in all the way until you hear or feel it click. The machine will not run if the drawer is not fully seated. Next, make sure the bonnet is sitting evenly on the base—if it is tilted or loose, the safety switch will prevent the cycle from starting. Press down gently on the bonnet to seat it properly.
If the light blinks red or the unit beeps, the sensors may be dirty or the globe may not be seated correctly. Remove the globe, wipe the sensors with a dry cloth, and reinstall the globe, making sure it clicks into place. If the unit still will not cycle after these steps, unplug it for 30 seconds and plug it back in to reset it. If problems continue, the motor or control board may need service from Litter Robot.
Frequently Asked Questions
Can I use water to clean the inside of the Litter Robot?
No. Water can damage the motor, sensors, and electrical components. Use only a dry cloth or a microfiber cloth barely dampened with water, and only on the globe and bonnet. Never pour water into the base or spray the unit with a hose.
How often should I replace the entire unit?
With regular maintenance, a Litter Robot typically lasts five to seven years. If the motor fails or the control board stops working, you may need to replace it sooner. Keeping the sensors clean and the filter fresh extends the life of the machine.
What should I do if litter is leaking out during the cycle?
Check that the bonnet gasket is intact and seated properly in its groove. If it is cracked or hardened, replace it. Also make sure the globe is fully inserted and the bonnet is latched down evenly. If litter still leaks after these checks, the globe may be cracked and need replacement.
Is it normal for the unit to be loud during the cleaning cycle?
Yes. The cleaning cycle is noticeably loud as the globe rotates and the internal mechanisms move. If the noise changes suddenly or sounds like grinding or scraping, stop the cycle and check for stuck litter or debris inside the base.
Do I need to use a specific type of litter in the Litter Robot?
The unit works best with clumping litter that forms solid balls. Avoid very fine dust-heavy litters, which can clog the sensors, and do not use crystal or non-clumping litters. Check your unit's manual for the recommended litter type and weight range.
